We made one of these 5 yrs ago, and used the bottom of an old grill for the pit. Just cut off the legs, and placed it into the center of the pavers, and we use the lid from the grill to cover it to keep the ambers from flying out. Works wonderful, and you can pick it up to dump the ashes. We enjoy it every night we can. Made our daughter and son-in-law one, too.
